Hey Guys,
Recently had a customer trying to power RB951G-2Ghnd using POE from a Dlink DGS-1008P which is a POE switch with 802.3af/at but the unit could not power at all ..
has any one had this issue..
dlink switch supports 802.3af PoE (48 volt)
rb951G supports passive PoE (8-30volt)
Hey not According to their product sheet,
Power Over Ethernet (PoE)
The first four ports of the switch support the IEEE 802.3af PoE and 802.3at PoE+
standards. Each of these four ports can supply up to 30 W for a total PoE budget
of 68 W, allowing users to attach multiple IEEE 802.3af/at compliant devices to the
switch. Use PoE for applications that are far from power outlets, or to minimize the
clutter of extra cables. When an end-device is not PoE-compatible, the D-Link
DPE-301GS PoE Splitter may be used to split DC power from the data signal at the
end device.

Chechito already gave a clear answer, the DLINK can’t power a Passive PoE device, since it needs 9-30V, not higher.
